Really?!In my opinion going to a bigger case than the fireball case is a waste of powder.
I made my own jig that holds 10 cases at a time and I cut with a carbide cutting wheel. I started with the Vartarg in 1995 just after Todd Kindler introduced it. My first action was a Sako L461 repeater but I did one on an XP100 single shot. The little Sako action feeds them smooth as butter without taking your eyes off the scope. Done the 20/222, 20/223, 20 PPC, and the 20 Tactical which I thought those cases were better suited for the 50 grain bullets. For shooting prairie poodles all afternoon nothing beats the 20 Vartarg with 40gr bullets. On a light wind day I can get a great shooting percentage out to 400+ yards.Greetings gentlemen,
first, thank you all for replying, I appreciate it.
My mentioning the 20-222 was due to (1) my indecision between the 0.20 based either on the 221 case or the 222 case, both of which I had been collecting, but not long enough, and (2) the initial reaction to Sniper338 post that Lapua discontinued making the 221 cases. So, your support for the 20-222 is not helping.
The reason for finally selecting the 221 case was that I have a blind magazine Remington Fireball action, and there appears to be a consensus that this particular action does feed the 221 cases well. Once the current craziness abates (I hope) and I will be able to find another Remington 223 action, I might build either 222 or 20-222.
Hi 457ciSBC,
thank you very much for the details on the dies.
Hi LCazador,
I had also attempted to reform the 223 cases. See, https://forum.accurateshooter.com/threads/reforming-cases-issues.4015888/#post-37886659. My clever friend built a fixture that makes shortening the cases easy and, as importantly, relatively quick. As he has the cases, I cannot measure the thickness of the cases at the neck, but I would think that since the neck is formed from a part of the body, it will be rather thick. So, if I understand, neck turning will be required.
L.Sherm already kindly advised me what tool he is using, but if you can also let me know, it would be great.
Kindest regards,
M
I am picking up my Cooper Firearms 20VT on 5/13. My 221 Fireball is dusty.Greetings all,
after changing my mind about million plus times, I have now finally settled on a .20 based on 221 case. According to my reading and inquiries, the main difference - as I understand it, is in the shoulder angle - 23deg vs 30deg and, consequently, a minor difference in volume.
The information regarding the effect on shoulder angle (case growth) is inconsistent, both camps arguing that it is negligible.
So the first question is - what is the availability of dies for either cartridge? Related to that, what would be the appropriate die to resize the 221 case for both; could you please give a specific example what you are using?
Is there a good place to rent a reamer? (If anyone has one to sell for a reasonable price, please let me know).
Kindest regards,
M
Just me, but I keep it simple: parent case, standard bushing die with a 20 cal bushing (plus one more in-between bushing for initial neck down). So, Redding 221 full length type S sizer with a 20 cal stem and proper bushings. No fireforming. I did it for 20 Practical (3 times), but a buddy did it for 20 Fireball. If they were any more accurate, we would need smaller prairie dogs.
Do you have any pictures of your trim jig?I made my own jig that holds 10 cases at a time and I cut with a carbide cutting wheel. I started with the Vartarg in 1995 just after Todd Kindler introduced it. My first action was a Sako L461 repeater but I did one on an XP100 single shot.

Just loaded more .221 Fireball ammo.out of curiosity, what did you move on?
M, you have tons of information from all these posts, and a huge amount to consider. You are not alone in this contemplation process. I can share that if you are confused about a decision, one way to consider things is, are you the person who wants to be fireforming brass and getting custom dies, etc? If so, then you can go with anything that tickles your fancy. If you want simplicity, and mostly want to shoot, go with a simple neck down of one you have mentioned, 20-221, 20-222, or 20-223. The latter two may be easier because of brass availability. The most common would be the 20-223 even though I am a .222 guy. Dies are easy for these as others have said. As far as a barrel and rifling, 1:11 twist seems the most successful. Bear in mind what bullets are available. The heaviest is the Hornady 45gr, but most common would be 32gr & 39/40gr. Other bullets would have to be custom right now. Those who have 20 Practical or 20-222 rifles, absolutely love them. In the bulletin portion of this site, or in the articles, there is a great article that had a few contributors. One was WarrenB who built a 20-223 (Practical), and others. There is also info. in the .20 cal tab. Reamers are easy. If you need info on that, just ask. Make sure the reamer design is fairly short for the 32gr bullets. Dies are easy for these simple neck-downs. You have plenty of time to ponder due to the unfortunate situation with materials availability. Everything is delayed.Hi NorCalMikie,
that is an interesting story. As I remember by perusing the saubier forum, several people have been working on the 20 TCM.
Kindest regards,
M
